You need to put the vars_mod_Beah!.txt file in the folder with the H2OUVE.exe file and execute the following command in an administrative command prompt in that folder:
H2OUVE.exe -sv vars_mod_Beah!.txt
H2OUVE will update the NVRAM area of the BIOS and after a reboot the new setting should be active.

I haven't seen the error 0x02 yet, but the other errors are normal.
They appear because some of the registers are read-only.
But in this case we only needed the setup-register and that was applied successfully, so that's fine.

If VirtualBox shows that AMD-V is enabled and you can use it properly, then I wouldn't worry about what the task manager shows.
If you want, you can do some more reboots and look if the task manager shows virtualization as disabled after any of them.
In case it does show virtualization as disabled again, dump the variables with H2OUVE to a new vars-file (vars2.txt) and upload it so I can take a look at it. You can use this command:
H2OUVE.exe -gv vars2.txt

In case you restore to default settings in the BIOS, you will probably have to apply the modded vars file again, but otherwise AMD-V should stay enabled.

You need to put the vars_mod_Adys32.txt file in the folder with the H2OUVE.exe file and execute the following command in an administrative command prompt in that folder:
H2OUVE.exe -sv vars_mod_Adys32.txt
H2OUVE will update the NVRAM area of the BIOS and after a reboot the new setting should be active.

First, you will need the tool: https://drive.google.com/file/d/0B4NHIBM...RtQXM/view
Extract the archive and go to the folder with the extracted files.
Then, you need to open an administrative command prompt in that folder (google it if you don't know how).
Execute the command from step 1 of the linked guide in that command prompt (H2OUVE.exe -gv vars.txt).
After that, you'll have the file "vars.txt" in that folder.
You need to upload this file, so that I can make the change.
